Indeed. Earlier this week, my wife and our 11 yr old daughter took our ETT puppy, Nemo, walking for the first time. He was very excited but quite nervous. We'd taken him to lots of places in recent weeks, although he stayed in our arms until Tuesday. In the playing field behind our house, he saw a couple of small dogs loose and carefully went over to them. He was quite respectful and not at all aggressive or over-bouncy! Then a big brown lab came charging across from the other side of the field and started going for Nemo! The owner (of all 3 dogs as it happens) made one perfunctory attempt at recall and when that failed just strolled in the opposite direction!

The other dogs joined in and poor Nemo was terrified, running in and out of my wifes legs trying to get safe until she managed to pick him up. My daughter says that she saw the lab get Nemo by the neck, although we can't see any marks.
My daughter was in tears, and since then poor Nemo has been *very* nervous when he's outside and whimpers when we head to the field or another dog comes near. His socialisation classes don't start until next Wednesday and I'm dreading his reaction.
